Playing Stardew Valley while having your favorite YouTube documentary, audiobook or podcast playing in the background.
Fast food ie McDonald’s quarter pounders with cheese and bacon, Wendy’s Baconators, French fries, fountain pop, etc, etc.
Sleeping all the day long.
Reading good books or ebooks ala Kindle or whatever program or method that you prefer.
Listening to music and constantly searching for new kinds of music that will appeal to your unique tastes.
Pirating all the old and new movies that you want from various darknet websites all while under the protection of a good VPN so your nosy ISP and copyright trolls can’t bring legal action against you.
Immersing yourself in the videogame emulation and or collector’s scene and trying to snag a rare beloved new old stock retro game from eBay or wherever else you may find such available from a hopefully reputable site or person.
As for the emulation scene you can literally use Hyperspin as a literal time sink to drain all your hours away endlessly configuring it and tailoring it more and more to your liking or simply trying to make your version of it as system and game complete as possible by finding as many complete rom and iso sets as you are able.
